Tupi class, German Type 209/3, 1500
 In the beginning of the 1980s Brazil decided, in accordance with the defense policy implemented then, to purchase new submarines for it`s Navy. It was then that the partnership with the German industry started. This partnership has resulted in the construction of four submarines for the Brazilian Naval Force: Tupi, Tamoio,Timbira, and Tapajo.
The lead of class was built by HowaldtswerkeDeutsche Werft (HDW) in Kiel, the last three were built by Arsenal De Marina, Rio De Janeiro by Brazilian technicians, who had acquired the required technical know-how during the construction of Tupi, in Germany.
The Tupi class is Type 209/3 displacing 1,400/1,550 tons surface/submerged respectively, the hull made of high yield steel, HY-80, with a diving depth of 820 feet.
Tupi, S-30, the lead of class, was launched on April 28, 1987 and commissioned May 6, 1989.
The Tamoio, S-31, the first submarine constructed in Brazil, was launched on November 18,1993 and commissioned December 12, 1994.
Tapajo, S-33, the last of class, launched June 5,1988, commissioned November 16, 1988
The Brazilen Post Issue
 This issue of the Brazilian Enterprise of Posts focuses on the launching of Tapajo Submarine, whose construction in Brazil represents the achievement of old aspirations of the Brazilian Navy. A naval vessel`s launching is the crowning of many people`s effort, for the considerable amount of time used in its construction. Particularly, this task becomes even more complex when it comes to submarines, due to the high level of sophistication demanded. Therefore, the pride which takes up the team in-charge is fair, as they realize such an accomplishment for the Brazilian naval construction. This merit is better evaluated by counting the number of countries that are capable of building a submarine.
Besides the prestige within the international community, which can be detected in political and commercial dividends
derived from the mastered technological skill, the present launching furnishes unquestionable credential to the
Brazilian industry that is supported by its performance in the operation of the two similar submarines preceding Tapajo.
Currently the Brazilian navy is busy constructing one unit of an improved Tupi-Tikuna class S-34 to be commissioned in 2007 and a more ambitious national project of constructing a nuclear powered submarine, SSN, in 2010- SNAC-2.
